django-crispy-forms:出现form_class但label_class和field_class却没有

Question

这是我第一次使用crispy-forms,我试图使用bootstrap 3基于ModelForm创建一个水平的crispy-form.在输出到模板"horizo​​ntal-form"显示但是"label_class"和"field_class".我查看了许多文档和stackoverflow,包括这个问题,似乎没有任何工作.

我的表格:

from django.forms import ModelForm
from panews.models import Story
from crispy_forms.helper import FormHelper
from crispy_forms.layout import Layout

class StoryForm(ModelForm):
    class Meta:
        model = Story
        fields = ['title', 'subtitle', 'content', 'variables']

    def __init__(self, *args, **kwargs):
        super(StoryForm, self).__init__(*args, **kwargs)

        self.helper = FormHelper()
        self.helper.form_method = "POST"
        self.helper.form_class = "horizontal-form"
        self.helper.label_class = "col-lg-2"
        self.helper.field_class = "col-lg-8"
        self.helper.layout = Layout(
            'title',
            'subtitle',
            'content',
            'variables',
        )

这是模板:

{% extends "base.html" %}
{% load crispy_forms_tags %}

{% block main %}

            <div class="container">
                        {% crispy form %}
            </div>

{% endblock %}

这是输出:

<main>

            <div class="container">


<form  class="horizontal-form" method="post" ><input type='hidden' name='csrfmiddlewaretoken' value='phDTwXgeNifQ8DJT8VWtG2stLEDA4LQS' /> <div id="div_id_title" class="control-group"><label for="id_title" class="control-label requiredField">
                Title<span class="asteriskField">*</span></label><div class="controls"><input class="textinput textInput" id="id_title" maxlength="50" name="title" type="text" /> </div></div><div id="div_id_subtitle" class="control-group"><label for="id_subtitle" class="control-label ">
                Subtitle
            </label><div class="controls"><input class="textinput textInput" id="id_subtitle" maxlength="50" name="subtitle" type="text" /> </div></div><div id="div_id_content" class="control-group"><label for="id_content" class="control-label ">
                Content
            </label><div class="controls"><textarea class="textarea" cols="40" id="id_content" name="content" rows="10"></textarea></div></div><div id="div_id_variables" class="control-group"><label for="id_variables" class="control-label ">
                Variables
            </label><div class="controls"><textarea class="textarea" cols="40" id="id_variables" name="variables" rows="10"></textarea></div></div></form>

            </div>


</main>

这是关于堆栈溢出的第一个问题所以请让我知道如何改进未来的问题或我的研究方法.

谢谢,内森

附加到settings.py

CRISPY_TEMPLATE_PACK = 'bootstrap3'
